He woke slowly feeling content and hungry. He felt something move under him as an arm wrapped around his waist. He rolled off his dear sister pulling a few pubic hairs as he separated from her. Her chest was healed and she was smiling at him. She was still in the spread and ready position trying to retain his sperm. The sheets were bloody and semen stained as were they both. Her pussy was gaping, still torn from their workout. A large mass of his cum was hanging out of her, thick from drying all night. As he watched, her he noticed her breasts were swelling even more. Her nipples were beading milk and her belly was definitely mounded. He knelt between her legs and held her belly. There was a kick from inside. As his heart leapt for joy something fell from his limp cock. Her womb had been ripped from her and was still on him until just then. He spread her pussy lips open and looked. She had grown a new womb, and it was occupied.
"I hope it's a girl", she said, "because I don't think I could handle two of you at once. Besides you need more pussy to screw and I don't mind sharing"
He wanted to fuck her so bad again but he could not get hard. He looked at her bloody womb laying there and he thought how delicious it must be. He picked it up, still full of her blood and sucked it dry. It was burning down his throat and his stomach lurched. There was a loud ringing in his ears and he kept hearing "EAT, EAT, EAT"
He shoved her uterus into his mouth chewed and swallowed. His head ached from the screaming,"MOOORRE".
He looked hungrily at her pussy. Her bruised and bloody clitoris was exposed fully on one side of her tear. He leaned down licking it til it responded swelling painfully for her, then he began chewwing it, swallowing the fluids and flesh as he gnawed it loose. She stroked his hair as he ate her, enjoying the sensation, knowing that he would be reawakened with this new food. After cannibalizing the right side of her pussy down to her groin muscle, he was satiated. He kissed her lips smearing her blood on her mouth, and suddenly felt his orgasm coming. He sat up grabbed his penis and aimed it into her open vagina. He watched as her body absorbed his cum and rapidly regrew the beautiful little pussy.
Panting, he asked, "How was that brat?"
She just smiled and giggled.
Their mother came in and changed the bedding. He thought it strange when she found a puddle of his cum and she carefully scooped it into a bottle....
